Launch configuration dialog

Launch configurations can most easily be visualized by looking at their
corresponding UI. Users interact with a launch configuration dialog to
create instances of the different types of launch configurations that have been
contributed by plug-ins. Each type of launch configuration defines a group
of tabs that collect and display information about the configuration. The
tab group for running a local Java application is shown below.

It's possible that a some tab groups are only appropriate when launching the configuration in a particular mode. If this is the case, then
one or more mode elements can be specified along with the class. For each mode, the tab group can be given a unique description.
If no mode is specified, then the tab group will be shown on all modes that
do not have a mode-specific tab group contribution. The Java application tab group is defined for run and debug modes:

Note that a perspective may also be specified with a mode. This will cause the platform to switch to the specified perspective when
the program is launched in that mode.

Your tab group class is responsible for creating the necessary tabs and
displaying and saving the relevant data from the launch configuration
attributes. A tab that is common to all configurations, CommonTab,
is already implemented and can be created by any configuration. This tab
manages the saving of the launch configuration as well as collecting common
preferences.
